Practical Shock Analysis & Design
At the first Shock and Vibration Symposium in 1947, mechanical shock was defined as "a sudden and violent change in the state of motion of the component parts or particles of a body or medium resulting from the sudden application of a relatively large external force, such as a blow or impact." Since then the specific words used have changed somewhat but the meaning remains the same. Most analysts treat shock as a transient vibration. No matter how it is described or what source produced it, the effects of mechanical shock on structures and equipment create major design problems for a wide variety of systems The course will be especially useful to those concerned with shock design and/or qualification of equipment for U.S. Navy ships such as the DDG 51, DDG 1000, LPD 17, submarines, aircraft carriers, and ship class extensions and upgrades.
This course will provide a comprehensive treatment of practical shock design and analysis with special emphasis on applications related to the design of ship structures and equipment for shock loads produced by underwater explosions.
Participants in this course will have an opportunity to increase their knowledge and understanding of the analytical and experimental tools that are available for shock design and qualification particularly with respect to requirements that are imposed for shipboard equipment. The lectures will provide a basic review of vibration and shock theory and will present the analytical and experimental methodology in the context of particular design applications. Analytical lectures will emphasize the physical significance of the results. Examples and case histories will be used as illustrations of design approaches; workshop problems that involve class participation will be used to advantage throughout the course. Class members will be encouraged to propose real design problems. The instructors will provide guidance for solutions or the problems may be used as class exercises.
Although this course is aimed primarily at shock design applications on ships, the analysis and design techniques presented are equally applicable to problems related to design for seismic loads or blast induced ground shock. Thus, engineers in these related areas may find the course to be useful. For all who participate, the course will provide a comprehensive coverage of shock design practice and a solid basis for further exploration of shock technology.

G. D. Hill
Mr. Hill has over 35 years experience in ship survivability and weapons effects, concentrating in underwater explosion (UNDEX) analysis, design, qualification, and testing. He has extensive experience in: application of analytical techniques for simulation of weapons effects and UNDEX events, test and measurement methods, and development and optimization of design for multiple operational and environmental requirements. He has participated in UNDEX design, qualification, and verification efforts on every major U.S. Navy surface ship program since the early 80’s. He is currently employed at Alion Science and Technology in Alexandria , Virginia . He has a Masters degree in Mechanical Engineering and is a Registered Professional Engineer.
Jeffery A. Morris
Mr. Morris is a Mechanical Engineer and has served HI-Test Laboratories, Inc., as a test engineer for over 30 years. He regularly designs interface test fixtures and auxiliary systems to support lightweight and medium weight shock testing and vibration test operations. He has designed special test platforms and unique auxiliary systems. Mr. Morris leads lightweight, medium weight and vibration testing from designing fixtures to writing the test report. Mr. Morris’ excellent organizational skills have afforded him the opportunity to coordinate all planning and scheduling for test projects issued HI-Test. He serves as lead engineer for MIL-STD-167 vibration testing, MIL-STD-740 structural and airborne noise testing, and MIL-S-901D lightweight and medium weight shock testing.
